I searched high and low a while back for both beards and mustaches with no luck. Online searches, stores, I even talked to a professional costume shop that supplies local playhouses.
Everyone I talked to said I should just use crepe hair and apply it myself. It's the cheapest, and with practice the most realistic.
I was told that even the best fake ready-made mustaches look, well, fake.
I've used muttonchops and wigs from this place and have been happy with the quality..they mostly do wholesale, but write & ask if they will sell direct or give you a distributor name if you like any of these:
any chance of good beards and wigs too? Im thinking on cutting my hair short and shaving my beard, but I want to have a beard and longer hair on occasion. Any help?
